Fibrin sealant applicator systems are provided for dispensing a first and a second protein solution to form a biological adhesive. The fibrin sealant applicator systems (10) according to the present disclosure include two piston-type sub-assemblies (14) coupled to two vials (62) storing the fibrinogen, and thrombin via a coupling unit (56). The piston-type sub-assemblies (14) store sterilized water within reservoirs (12) which are in fluid communication with the vials (62) via the coupling unit (56). The water is forced into the vials (62) to form the fibrinogen, and thrombin solutions. The solutions are then drawn into the reservoirs (12), and a Y-coupler (86) is attached to the distal end of the piston-type sub-assemblies (14). The Y-coupler (86) provides fluid communication between the reservoirs (12), and a nozzle body (94) for dispensing the solutions when distal pressure is created within the reservoirs (12) to force the solution towards the nozzle body (94). |
